Four new mystery charts every day, with the satisfaction of figuring out what the data represents from clues alone.
Fauxlio
What is Fauxlio?
Fauxlio is a daily literary game about distinguishing human writing from AI-generated text. Each round presents a short book excerpt and an AI rewrite of the same passage, and players must decide which one is the human original.

Perfect little brain warm-up for a coffee break—just you, a passage, and a gut feeling for which one a person actually wrote.

The format is clean and the premise is solid, but the challenge lives or dies on whether the AI rewrite is tricky enough to actually fool you.

I want a daily score, a streak, maybe a success rate—give me the numbers so I can track whether my human radar is actually improving.
How to play Fauxlio
Read the two passages, then choose either the first text or the second text depending on which you believe was written by a human. After your guess, the game reveals the source; you can continue through the day's rounds, build a daily score, or switch to ∞ mode for more play.
Tips & strategy
- Hunt for small quirks: unusual word choices, awkward phrasing, or personal details are often signs of human authorship.
- AI rewrites frequently sound polished and generic, so be suspicious of writing that is grammatically perfect but bland.
- Compare sentence rhythm; human writing tends to vary structure more than an AI rewrite.
- Pay attention to the passage's literary context or period, as human originals may contain references or style choices an AI rewrite would smooth over.
- If one version is noticeably 'cleaner' than the other, consider whether that neatness is the mark of an AI rewrite.
